Abstract: Disclosed are methods and systems for configuring service of a user equipment device (UE). When the UE has dual-connectivity service, such as EN-DC service, high quality on one of the UE's air-interface connections could result in transition of the UE to operate in discontinuous reception (DRX) mode on the UE's other air-interface connection.

Abstract: A method and system for a base station (BS) configured for sharing among a plurality of public land mobile networks (PLMNs), and for providing open radio access and/or closed subscriber group (CSG) radio access for user equipment devices (UEs) served. The BS may make a determination of which PLMNs have enabled CSG and which have not, and may transmit a request to a core network of each PLMN to set up an interface connection with each. Based on the determination, the request may either include information for configuring CSG radio access, or information for configuring only open radio access. For each PLMN having CSG enabled, the interface connection may be established for CSG radio access for UEs associated with PLMNs having CSG enabled. For each PLMN not having CSG enabled, the interface connection may be established for only open radio access for UEs associated with PLMNs without CSG enabled.

Abstract: A method and a system for concurrently transmitting from an antenna a first sequence of data from a first access node and a second sequence of data from a second access node. An example method includes orthogonally encoding the first and second sequences, including encoding the first sequence with a first binary code to produce a first encoded sequence and encoding the second sequence with a second binary code to produce a second encoded sequence, combining the first encoded sequence and the second encoded sequence to produce a combined encoded sequence, and transmitting the combined encoded sequence from the antenna, with transmitting the combined encoded sequence from the antenna including engaging in a first transmission of the combined encoded sequence from the antenna and engaging in a second transmission of the combined encoded sequence from the same antenna with a phase delay compared with the first transmission.

Abstract: A method for controlling configuration of an air interface between an access node and at least one user equipment device (UE), where the air interface is divided over time into frames and the frames are further divided at least into subframes, where the air interface operates in accordance with a time-division-duplex (TDD) configuration that defines at least a number of uplink subframes per frame for communication over the air interface. An example method includes (i) detecting at least a threshold high rate of uplink voice muting on the air interface, and (ii) responsive to at least the detecting, changing the TDD configuration to increase the number of uplink subframes per frame over the air interface.

Abstract: A mechanism to help control connectivity of a user equipment device (UE). When the UE is served by a master node (MN) that does not support VOP service, the MN will cause the UE to not have a secondary connection with a secondary node (SN) that would engage in control-plane signaling with the UE via the UE's master connection with the MN. For instance, in that situation, the MN could avoid setting up the secondary connection for the UE in the first place. Or if the secondary connection exists already, the MN could tear down that secondary connection. By causing the secondary connection to not exist, the mechanism may help to avoid problems with operation of the secondary connection as a result of the UE tuning away to facilitate voice service.

Abstract: A method and system to help facilitate communication between a user equipment device (UE) and an access node that is serving the UE, in a scenario where a bearer is configured for the UE, the bearer having a defined set of quality-of-service (QoS) requirements for communication of user-plane data on the bearer. When wireless coverage of the UE from the access node is threshold poor, the access node and a supporting core network could interwork to loosen the set of QoS requirements of the bearer in an effort to avoid loss of the bearer. And upon loosening of the set of QoS requirements, the access node could invoke Packet Data Convergence Protocol (PDCP) duplication for the communication between the UE and the access node on the bearer, to help improve quality of the communication between the UE and the access node in presence of the threshold poor wireless coverage.

Abstract: A method and system for controlling operation of a first access node that supports operation according to a first radio access technology (RAT) but does not support dual-connectivity operation according to the first RAT and a second RAT. A controller detects a high extent of occurrences of dual-connectivity-capable user equipment devices (UEs) being connected with the first access node when the dual-connectivity-capable UEs could instead connect with a second access node that supports the dual-connectivity operation. And in response, the controller suppresses coverage of the first access node, such as by reducing a maximum signal delay that the first access node applies for determining whether to accept random-access requests from UEs and/or (ii) reducing reference-signal transmission power of the first access node.

Abstract: A method and system for controlling data split of a dual-connected user equipment device (UE) when the UE has at least two co-existing air-interface connections including a first air-interface connection with a first access node and a second air-interface connection with a second access node. An example method includes (i) comparing an aggregate frequency bandwidth of the first air-interface connection with an aggregate frequency bandwidth of the second air-interface connection, (ii) based at least on the comparing, establishing a split ratio that defines a distribution of data flow of the UE between at least the first air-interface connection and the second air-interface connection, and (iii) based on the establishing, causing the established split ratio to be applied. Further the method could include using the comparison as a basis to set one of the UE's air-interface connections as the UE's primary uplink path.

Abstract: In a system where a first node provides a first area of TDD coverage on a first TDD carrier using a first TDD configuration and an adjacent second node provides a second area of TDD coverage on a second TDD carrier using a different second TDD configuration, the first node could additionally provide an area of FDD coverage on a first FDD carrier, including causing the area of FDD coverage to sit at least partially between the first and second areas of TDD coverage and therefore to define a spatial buffer between the first and second areas of TDD coverage. For instance, the first access node could restrict its service on the first TDD carrier to be for user equipment devices (UEs) that are relatively close to the first access node and could restrict its service on the first FDD carrier to be for UEs that are relatively far away from the first access node.

Abstract: A method and system for controlling application of split-uplink mode in a wireless communication system including an access node. In an example implementation, a method includes determining a first count defining how many user equipment devices (UEs) are connected with the access node and do not support a split-uplink-mode operation in which uplink user-plane data flow is split between air-interface transmission to the access node and air-interface transmission to another access node. Further, the method includes determining a second count defining how many UEs are connected with the access node as part of dual connectivity and support the split-uplink-mode operation. And the method includes, based on the first count and the second count, controlling whether the access node will allow the split-uplink-mode operation, such as whether the access node will allow new activation of the split-uplink-mode operation.
